WASHING MACHINE FOR THE EXTERIOR OF' BOTTLES PARTICULARLY SIPHONS Filed Sept. 5, 1935 INVENTOR ATTORNEY Patented Aug. 11, 1936 UNITED STATES PATENT OFFICE WASHING MACHINE FOR THE EXTERIOR OF BOTTLES, PARTICULARLY SIPHONS 1 Claim.

The object of the invention is to provide a washing or scrubbing machine for the exterior of bottles, particularly bottles which, because of their construction are difficult to clean, siphons being of this type.

A characteristic of the device is its inherent simplicity and the visibility of operations. It incorporates only one moving element, the rotary tumbling disk upon which the bottles are directly supported.

The invention will be described with reference to the accompanying drawing, in which Figure 1 is a perspective view, partly broken away, of an embodiment of the invention.

Figure 2 is an enlarged sectional elevation on the line 22, Fig. 1, partly broken away.

Referring to the drawing, it will be seen that the device comprises a cylindrical tank having a fixed bottom wall I and an annular vertically extending side wall 2. The tank may be made entirely of metal and secured by welding, rivets, or bolts, to the supporting legs 3.

Within the tank and at a substantial distance above bottom wall I, are a plurality of fixed bracket arms 4 to which are connected radial plates 5, the plates in turn being secured to bars 6 carrying a fixed bearing member 1 for a shaft 8.

Carried by each plate 5 is a radially extending brush 9 and an adjacent brush l extending at generally right angles to brush 9. These brushes may have their bristles arranged in curvatures in order to conform with the curvatures of the bottles to be scrubbed.

Shaft 8 is projected downwardly through the bottom wall I of the tank and the aperture therefor may be suitably protected by packing material. The shaft passes through .a suitable packing sleeve H secured by flange Ha: to bottom wall I, and thence is carried within a gear housing l2. The shaft will carry a worm gear (not shown) connected to a worm (not shown) on a shaft l3 driven by motor M, the motor resting on a platform l carried by bracket arms connected to legs 3.

Disposed within the tank below arms 5 and fixed to shaft 8 as by set screw I5, is a rotating tumbler disk I6 carrying at its top a cork or other somewhat yielding surface material Him. The bottles, as, for example, siphons, are each placed with its bottom wall adjacent a brush Ill and its side wall adjacent a brush 9, the tank previously having received a washing liquid, as, for example, water.

The operation of motor I4 will rapidly rotate the tumbler disk I6, and the bottles will be given a rotation because they will be drawn into abutment with the brushes and the gripping surface of the tumbler disk will frictionally act as a 5 wheel for rotation. In order to secure the necessary friction between the tumbler disk and the bottles, the surface I6 thereof may be made of any material in addition to cork which will act as a brushing or cleansing medium, as, for ex- 10' ample, cocoa mat.

Dirt and other bottle surface material scrubbed from the bottles will be carried by the agitation of the liquid to the periphery of the tumbler disk and thence will descend by gravity to the bottom of the tank below the disk.

It will be understood that various modifications may be made in the form and arrangement of the elements comprising the embodiment illustrated in the drawing without departing from the spirit of the invention. What I claim and. desire to secure by Letters Patent, is as follows:-

A washing and scrubbing machine for the exterior of bottles and the like, comprising a cylindrical tank adapted to contain liquid, a rotating disk within the tank substantially spaced from the side wall of the tank and. having a yielding surface, a shaft projected vertically through the bottom wall of the tank and fixed to the rotating disk, the shaft projecting substantially above the disk, a spider fixed to the walls of the tank and consisting of a plurality of spaced arms arranged radially of the tank and a central bearing member carried by the arms and receiving the shaft,

a plurality of brushes carried by the arms of the spider, the bristles being held in substantially horizontal position, supplemental brushes arranged at the inner sides of the tank angularly of the first named brushes and in juxtaposition therewith, means for rotating the shaft whereby 4 the bottles are carried forcibly against the brushes and are given a rotational movement by frictional contact with the yielding upper surface of the rotating disk, and means for maintaining a body of quiescent liquid within the tank for agitation at its upper level by the rotating disk comprising a liquid-tight bottom wall carried by the tank at a substantial distance below the rotating disk, thereby supporting a relatively quiescent part of the body of water for receiving 50 and holding sediment.
